In Ethiopia, stem rust caused by Puccinia graminis f. sp. tritici (Pgt) is one of the most serious wheat diseases. On vulnerable cultivars, it has ability to cause yield losses up 100%. The infection responses forty-two lines at seedling stage against eleven isolates race TTKSK (Ug99 race), TTRTF, TKTTF (Digalu JRCQC, TKKTF, TRTTF, TTTTF, TTKTF, TTKTT, RRTTF, and TKPTF were evaluated in a study...

The damage to wheat crops by stem rust poses a threat the food security of world’s population. species Thinopyrum ponticum (Podpěra, 1902) (Z.-W. Liu and R.-C. Wang, 1993) is non-host for fungus Puccinia graminis f. sp. tritici Eriks. Henn. (Pgt). Sr24, Sr25, Sr26 genes, transferred from Th. gene pool, protect cultivars disease in different regions world. study resistance (NHR) effects introgre...

Proteins in intercellular washing fluid (IWF) from wheat (Triticum aestivum) and barley (Hordeum vulgare) leaves were separated by two-dimensional isoelectric focusing-polyacrylamide gel electrophoresis and stained with Coomassie brilliant blue (CBB) or silver. Intracellular protein from the cut ends of leaves accounted for only a small proportion of total protein in IWF from wheat leaves. When...

Stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), has potential to cause major yield losses in durum wheat. Development of cultivars with improved resistance stem rust is a sustainable option for effective control this disease. This study was conducted identify genomic regions associated Ug99-derived Pgt races using doubled haploid (DH) mapping population produced from cross between ...
